Checking if a string contains all or any elements of a list

[k1llcod3]

so i have some keywords in a list and i want to check if a string contains any or all of those keywords. E.g

teststring = 'this is a test string it contains apple, orange & banana. Moreover, this i a very long string contact length more than 500k'
keywords= ['apple','banana'.'length']

i want to do something like,

if (any or all elements in keywords) in teststring:
    print("Match found")

i found a way using any():

if any(ext in teststring for ext in keywords):
    print("Match found")

so the prob. with that is that it can be slow if string is long like in my case contact length > 500k . Is there any better way to do both any or all operations?
